Results of PCR Analysis of Mpox Clinical Samples, Sweden, 2022

Abstract

We compared cycle thresholds from mpox skin lesions with other specimen sites and over time from onset of clinical signs among 104 patients in Sweden. Cycle thresholds differed by anatomic site. We identified 2 early mpox cases from anorectal swab specimens after skin samples were negative, indicating necessity of sampling multiple sites.
